Answer: B
Explanation: The colon is not correct, because what follows isn't a list. It should be written with a comma, like this: "Although she wanted to be in the play, she lacked self-confidence, so she didn't think she would get the part."
The sentence that is incorrectly punctuated is option B.
"Help me shovel the driveway please?"
The correct punctuation here is: "Help me shovel the driveway, please.
This is a request, so we use a comma before the word "please", that is used to make the request polite, not a demand or an order. The period is used at the end because the person is not making a question, but making a request.
